Cylindrical Roller Bearings FAG NJ2215 -E-XL-TVP2-C3

The FAG NJ2215 -E-XL-TVP2-C3 cylindrical roller bearing offers high radial load-carrying capacity with dimensions of 75x130x31 mm and increased C3 clearance.

The FAG NJ2215 -E-XL-TVP2-C3 cylindrical roller bearing is a single-row radial roller bearing designed for demanding industrial applications. With a bore of 75 mm, an outer diameter of 130 mm and a width of 31 mm, the design can withstand very high radial loads. The line contact of the cylindrical rollers gives the component high rigidity. The open bearing operates without an integrated seal and is suitable for a temperature range of -30 to +120 degrees.

In which installation scenarios is the NJ2215 -E-XL-TVP2-C3 cylindrical roller bearing used?

Designs subject to high radial loads and single-sided axial guidance specifically utilise the NJ design as a support bearing. Typical applications include shaft mountings in mechanical engineering where transverse forces predominate. As the inner ring can be removed from one side, the roller bearing can be fitted separately onto the shaft and housing. The bearing transmits high radial forces, supports axial loads from one direction and allows axial displacement in the opposite direction.

What is the function of the polyamide cage and the C3 clearance in this design?

The polyamide material in the TVP2 cage reduces the moving mass of the roller guide and contributes to low-vibration operation. The suffix C3 indicates a slightly increased radial clearance. This increased radial clearance compensates for operational heating and tight shaft fit oversizes, ensuring that the rollers do not jam. Manufactured to tolerance class P0/PN or ABEC 1, the component meets standardised specifications for dimensional and concentricity tolerances.
